With regard to the weight of the flywheel in the 100 I doubt that a lot of =
design went into optimization of that detail at the time the flywheel was s=
pecified. Remember the origins of that engine which was a truncated versio=
n of the 6 cylinder Austin lorry engine. It was originally supposed to be u=
sed as a wartime replacement for worn out engines in Willys Jeeps should su=
ch become necessary. The war ended before such replacement was needed and s=
o Austin ended up with a surplus of these engines in search of a purpose. U=
nder those circumstances I would guess that the flywheel used on these engi=
nes was carried over from the Austin 4 liter lorry engine.
If that is the case then there would be a lot of excess steel that can be s=
afely shed for a smaller engine in a light weight vehicle such as an Austin=
Healey.

I put a flywheel of the early 6 cylinder on my 100- probably about half the=
weight of the original.
Motor was a little more than M-spec with flat top pistons.
Made it more lively boy no difference in tractability.
I must admit I never revved it hard, there being no need to.
A good mod in my opinion

Michael,
Thanks for the informative article. What is the affect of a lighter flywhee=

I encourage as many people as possible to "M" up their 100's.
Makes original cars that much more valuable.
